We analyse households’ responses to an unanticipated change in consumption opportunities and evaluate their implications for the nature and formation of preferences. We study the tariff experiment conducted by South Central Bell where local telephone measured tariffs were introduced for the...

The determinants of the dramatically rising expenditures on health care in general, and on hospital care in particular, have been of prior concern to policy and to research. Using a rich panel data set this paper contributes to this literature by investigating factors determining the demand for...

Many empirical gravity models are now based on generalized linear models (GLM), of which the Poisson pseudo-maximum likelihood estimator is a prominent example and the most-frequently used estimator. Previous literature on the performance of these estimators has primarily focussed on the role of...

This Paper looks at public sector pay in Britain. We present a novel instrument that exploits the variation in public sector status across individuals arising from the privatisation programme of the 1990s. We show formally that results that are estimated may thereby be robust to self-selection...

We study the relationship between urban sprawl and obesity. Using data that tracks individuals over time, we find no evidence that urban sprawl causes obesity. We show that previous findings of a positive relationship most likely reflect a failure to properly control for the fact the individuals...

Instrumental variable estimation requires untestable exclusion restrictions. With policy effects on individual outcomes, there is typically a time interval between the moment the agent realizes that he may be exposed to the policy and the actual exposure or the announcement of the actual...

The existing literature on inequality between private and public sectors focuses on cross-section differences in earnings levels. A more general way of looking at inequality between sectors is to recognize that forward-looking agents will care about income and job mobility too. We show that...

We study the effects of a conditional cash transfers program on school enrollment and performance in Mexico. We provide a theoretical framework for analyzing the dynamic educational process including the endogeneity and uncertainty of performance at school (passing grades) and the effect of a...

Conventional methods for analysing worker flows often focus on gross flows or transition probabilities. This is not necessarily informative for identifying the scale of labour ‘adjustment’ in an economy in the sense of the expansion and decline of industries. We develop a method that relates...
